38 Study Guide for An Introduction to Chemistry Section Goals and Introductions Now that you know about atoms, elements, chemical bonds, and chemical compounds, you are ready to be introduced to chemical changes and the ways that we describe them. Section 4.1 Chemical Reactions and Chemical Equations Goals To describe the nature of chemical reactions. To show how chemical reactions can be described with chemical equations. To show how to balance chemical equations. This section starts with a brief description of chemical reactions. The introduction to chemical reactions is followed by a description of how chemical changes are described with chemical equations. You will see many chemical equations in this text, so it is very important that you be able to interpret them. Sample Study Sheet 4.1: Balancing Chemical Equations describes the important skill of balancing equations so that they reflect the fact that the number of atoms of each element for the products of chemical changes always equals the number of atoms of each element in the initial reactants. Our Web site provides a tutorial that will allow you to practice balancing chemical equations. Internet: Balancing Equations Tutorial Section 4.2 Solubility of Ionic Compounds and Precipitation Reactions Goals To describe the process by which ionic compounds dissolve in water. To describe the changes that take place on the molecular level during precipitation reactions. To provide guidelines for predicting water solubility of ionic compounds. To describe the process for predicting precipitation reactions and writing chemical equations for them. This section begins by describing solutions in general, describing solutions of ionic compounds in particular, and most important, describing the process by which ionic compounds dissolve in water. If you develop the ability to see this process in your mind’s eye, it will help you understand the process of chemical changes between substances in solution. An animation on our Web site will help you to visualize the process of dissolving sodium
